sure, alcohol and drugs do still affect a child quite intensely, though I'm saying that, is social media and the endless dopamine harvesting NOT a drug? if you think about it, it extracts, makes a person want to come back for more, causing addiction, further extracting more, losing its effectiveness and making it almost impossible to quit from there.

I don't think you understand what drugs are or can do. They don't all just blindly increase dopamine. They have many other effects on the mind and body that social media does not. This whole concept of dopamine detoxes and addiction = dopamine needs to die too. It's not based on solid scientific understanding as addiction is far more complex than this and comes in multiple, separate forms. Even drugs like amphetamines that primarily interact with the dopamine system don't always lead to addiction (ask anyone with experience of ADHD meds). Thinking dopamine is only about addiction and vice versa is like thinking electricity is only for heating and that all heating must be done using electricty.

Raising children without access to the internet is both backwards for their education and actively dangerous. The internet has allowed minors in bad situations to escape or get help multiple times. It's also made people realise their parents or guardians are insane or abusive including those who are members of dangerous religions and cults, are homophobic, or are abusive for other reasons. School in some countries is also packed full of propaganda, and even when it isn't they can't always help and are sometimes a source of abuse themselves. Restricting access to information isn't a good thing.
